Przebieg Zmienności Stężeń Wybranych Zanieczyszczeń W Gazach Odlotowych Z Procesu Mokrego Gaszenia Koksu, Marian Mazur, Robert Oleniacz, Marek Bogacki

Robert Oleniacz

Continuous measurement results of selected constituent concentrations in the gases emitted to the air during the coke wet quenching process were presented and discussed in the paper. The measurements were carried out for the standard wet quenching tower. The research covered such substances as carbon dioxide, carbon monoxide, hydrogen sulfide, nitrogen oxide, nitrogen dioxide and a total content of hydrocarbons and hydrogen (combustible gases). Changeability of the substance concentrations depending of the quenching process duration was analyzed. Among other things the beginning of these substances formation, appearance of the maximum and the range of observed concentrations were taken into consideration. …

Computer-Based Modules for Engineering Instruction Must Be Concise, Flexible, Educational and Engaging in Order to Effectively Supplement Traditional Classroom Teaching Tools. a Computer Example that Takes More Time Than a Chalkboard Presentation is Not Likely to Be Useful in Today's Engineering Classroom. Flexible Navigation is Necessary So that the Instructor Can Quickly and Easily Respond to Student Questions. Useful Modules Must Also Improve Problem-Solving Skills or Clarify Troublesome Concepts in Order to Be Considered Worthy of Inclusion in the Limited Class Time Available. Finally, and Perhaps Most Importantly, Effective Computer-Based Modules Must Meet the Challenge of Holding the Student's Attention. …

Upper Spokane River Model: Boundary Conditions And Model Setup, 2001, Spencer Slominski, Robert Leslie Annear, Chris Berger, Scott A. Wells

Civil and Environmental Engineering Faculty Publications and Presentations

The Washington Department of Ecology is interested in a water quality model for the Upper Spokane River system for use in developing Total Maximum Daily Loads (TMDLs). The goals of this modeling effort are to:

• Gather data to construct a computer simulation model of the Spokane River system including Long Lake Reservoir and the pools behind Nine Mile dam, Upper Falls dam and Upriver dam for 2001 based on the calibration conducted for 1991 and 2000 data sets, (Annear et al, 2001).

• Ensure that the model accurately represents the system hydrodynamics and water quality (flow, temperature, dissolved oxygen …

Applications Of Underground Structures For The Protection Of Critical Infrastructure, George H. Baker, Richard G. Little, Don A. Linger

George H Baker

The U.S. President’s Commission on Critical Infrastructure Protection (PCCIP), convened in the wake of the bombing of the Murrah Federal Building in Oklahoma City, concluded that the nation’s physical security and economic security depend on our critical energy, communications, and computer infrastructures. While a primary motivating event for the establishment of the commission was the catastrophic physical attack of the Murrah Building, it is ironic that the commission focused its attention primarily on cyber threats. Their rationale was that cyber vulnerabilities posed a new, unaddressed challenge to infrastructure security. This approach was further questioned by the events of September 11, …

Tmdls: Statistical Correlations Or Mechanistic Modeling?, Scott A. Wells, Thomas M. Cole

Civil and Environmental Engineering Faculty Publications and Presentations

In developing TMDL waste-load allocations for the Snake River-Reservoir system in Western Idaho and Eastern Oregon, determinations of the assimilative capacity of the system and the impact of pollutant reduction strategies has been performed using both a statistical-correlation approach and a mechanistic modeling approach. The system included the Lower Snake River, Brownlee Reservoir, Oxbow Reservoir, and Hells Canyon Reservoir with the focus was on Brownlee Reservoir.

The statistical approach used on Brownlee Reservoir divided the system into riverine and lacustrine zones. Field data were then averaged over season and location to provide statistical correlations, such as between total phosphorus (TP) …

Likwidacja Strefy Ochronnej Huty Katowice I Zakładów Koksowniczych "Przyjaźń" W Dąbrowie Górniczej, Marian Mazur, Robert Oleniacz, Marek Bogacki

Robert Oleniacz

Legislation changes in Poland concerning the protective zones (created around industrial plants particularly harmful to the environment) were presented in the paper. Conditions connected with forming, developing and partial elimination of the protective zone existing around the "Katowice" steelworks and the coke plant Przyjaźń in Dąbrowa Górnicza (Poland) since 1978 were characterized as well.

English title: Elimination of the protective zone of the Katowice steelworks and the coke plant Przyjaźń in Dąbrowa Górnicza.

Field Guide To The Geology Of The Harlan County Lake Area, Harlan County, Nebraska, With A History Of Events Leading To Construction Of Harlan County Dam, Robert F. Diffendal Jr., Duane R. Mohlman, R. George Corner, F. Edwin Harvey, K. J. Warren, Scott Summerside, Roger K. Pabian, Duane A. Eversoll

School of Natural Resources: Faculty Publications

The year 2002 will mark the fiftieth anniversary of completion of the Harlan County Dam and Multi-Purpose Reservoir. This seems a good time to write about the history of and reasons for building the dam, the effects of the dam and reservoir on the Republican River valley, and the geologic features seen along the shores of the lake and areas nearby. As many junior authors helped produced this educational circular, they are listed in the table of contents. All other sections were written by the senior author.

Includes July 2016 update: Addendum of photographs showing fault traces on drought-exposed lake …

Creep And Creep-Recovery Models For Wood Under High Stress Levels, Zhiyong Cai, Kenneth J. Fridley, Michael O. Hunt, David V. Rosowsky

Civil and Environmental Engineering and Construction Faculty Research

Forty small clear southern pine specimens were loaded under third-point bending to examine creep and creep-recovery behavior for wood under high stress levels. Stress levels of between 69% and 91% of the predicted static strength were applied for 23 h with 1 h allowed for recovery, and the resulting deflection vs. time behavior was studied. The experimental creep and creep-recovery behavior was modeled using modified power law functions. The results indicate that these functions provide the best fit to both primary and secondary experimental data. The empirical models can be used to simulate the viscoelastic behavior of wood under high …

Weryfikacja Emisji Pyłowej Z Huty Katowice I Zasięgu Jej Oddziaływania, Marian Mazur, Robert Oleniacz, Marek Bogacki, Agnieszka Łopata

Robert Oleniacz

Preliminary analysis of the results of atmospheric dispersion modeling for dust emission from the Katowice Steelworks (Poland) showed necessity of verification the particulate matter, lead and cadmium emission from the plant. The verification was limited to the substance emission sources influencing air pollution to the largest extent. Both scale of dust emission and its granulometric and chemical composition were re-evaluated. Further calculations of the air propagation for the pollutants were carried out and calculation results were compared with direct measurements. Thus the Katowice Steelworks impact on air quality and the level of total dust, lead and cadmium ground deposition was …

Wpływ Związków Metali Alkalicznych W Procesie Spiekania Rud Na Emisję Pyłów, Marian Mazur, Marek Bogacki, Robert Oleniacz

Robert Oleniacz

The work shows the impact of alkali metals in the sintering process on effectiveness of the electrostatic precipitator and dust emissions into the air. The results of analysis of the content of Na and K in dust discharged from the sinter strand and emitted to the air are presented. It was found that this content is subject to large fluctuations and significantly increases in the dust phase after electrostatic precipitators. Using the balance sheet data, the effect of loads of Na2O and K2O compounds contributed to the sinter mix on emissions of dust. It was also observed high variability of …
